I've noticed that since becoming a vegetarian I'm much less hungry than I was as an omni. I actually work to keep my calorie intake at a healthy level (I have a very physical job and burn lots of calories per day)....when, before, I was always snacking or over eating and stuggling with diets. I also rarely have cravings for anything.

I get low blood sugar between meals a lot, but I feel like my blood sugar has become a lot more stable. Of course, every now and then I still get light-headed and need to grab a snack, but it seems like it hasn't been happening nearly as often since going veg.
